And now, some limitations:
[At launch,] Vita Web Browser Can't Be Used While Playing Games

When I posted this, I had no way to verify the claim. Now that I tried Vita personally, I think there is a chance andriasang.com has misinterpreted the report.

[Correction]
The first occurrence article "Web browser and the game will run at the same time," and representations had been, from the SCE "Vita initial offering, the behavior of Web browsers and games will get exclusive access" in touch with you. Immediately after release, and simultaneous use of the Web browser is not game, I expect the response by the system software update.
It is possible that Sony was referring to multitasking above. i.e., if you're downloading/streaming a video from the web browser and swipe to another game, the web browser will essentially stop its network activities. "We can't run the web browser and the game at the same time".
When I toyed with Vita in SF last weekend, I could start the WebKit browser in the middle of a game, unlike PS3 XMB. Although the lack of memory card prevented me from going further (It asked me to insert a memory card), I could see the WebKit process in the opened applications list. In fact, I could swipe between six applications, including the game and browser. I was happy the swipe animation and tracking felt smooth and snappy, noticeably better than Android 2.*, slightly less sensitive than iOS.
When the game is the active app, I need to click on the "Continue" button to resume. It looks like the web browser can be used in-game, but we can only keep one active app at any time (at launch).
Would love to check it out again after Vita has launched in Japan; hopefully this time with US PSN, memory card, and all social apps enabled.
EDIT:
Sony, please change the polka dot menu and icons. They don't do the underlying system justice.
